Genes affected

POLE (HGNC:9177): (DNA polymerase epsilon, catalytic subunit) This gene encodes the catalytic subunit of DNA polymerase epsilon. The enzyme is involved in DNA repair and chromosomal DNA replication. Mutations in this gene have been associated with colorectal cancer 12 and facial dysmorphism, immunodeficiency, livedo, and short stature. [provided by RefSeq, Sep 2013]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.18672428).

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000854 (13/152218) while in subpopulation AMR AF= 0.000589 (9/15284).

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1382 of the POLE protein (p.Arg1382His). This variant is present in population databases (rs143229302, gnomAD 0.02%). This missense change has been observed in individual(s) with melanoma (PMID: 29641532). ClinVar contains an entry for this variant (Variation ID: 405766). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt POLE protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The POLE c.4145G>A p.(Arg1382His) missense change has a maximum subpopulation frequency of 0.020% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org). The in silico tool predicts a benign effect of this variant on protein function, and functional studies have not been performed. This variant has not been reported in the literature in individuals with POLE-related disease. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
